Procedure

137 mg (1.97 mmol) of hydroxylamine hydrochloride were added to a solution of 398 mg (0.879 mmol) of N-(2-t-butyl-5-carbamoylphenyl)-3-(4-formyl-2-methoxyphenyl)octanamide (prepared as described in Example 110) in 5 ml of pyridine, and the resulting mixture was stirred for 20 minutes. At the end of this time, the reaction mixture was diluted with water, and the diluted aqueous mixture was extracted with methylene chloride. The extract was dried over anhydrous magnesium sulfate, and the solvent was removed by distillation under reduced pressure. In order to remove the pyridine remaining in the residue, it was dissolved in toluene and the solvent was azeotropically distilled off. Repetition of this procedure gave 414 mg (a quantitative yield) of the title compound as a foam-like substance.
